after disabling Nvidia Geforce GT 540M, I unmerge Nvidia prority drivers " nvidia-drivers", then emerge "xf86-video-intel", however it doesn't work at all, I searched the issue, someone try "xf86-video-vesa" successfully, and I failed again, any suggestion appreciated, thanks very much

Rename the file to say, /etc/X11/xorg.conf_not_needed and run startx.
You may want parts of the file back later, so don't delete it yet.

Both the intel and vesa drivers work without a xorg.conf file, however you will get a USA keyboard layout.
On its own, Xorg will try the intel driver before the vesa driver.

If it fails, use wgetpaste to post both the new Xorg.0.log and your kernel .config file.
The intel driver only works if the kernel support is correct. That means some things on and others off._________________Regards,

Computer users fall into two groups:-
those that do backups
those that have never had a hard drive fail.

When I clicked "Application" in Gnome, it can't display applications list,
however, "Preferences" and "Administrator" work well, is it a bug in Gnome2.6?

I always used Intel integrated graphic card on Gentoo Linux before, but I found out that independence graphic card can't match well with Linux,
I will not buy any Nvidia graphic card on Notebook any more if I use Linux, or maybe all graphic cards are the same effect in Linux.

Welcome to Gentoo.

Your Xorg.0.log shows

Code:

[ 430.844] (==) Using config file: "/etc/X11/xorg.conf"

Are you really sure you have Gnome 2.6?
Gnome 3.2 is in stable Gentoo.

How do you start Xorg?
Do you use the startx command or a display manager?

Originally, notebooks with two graphics cards really had two graphics cand and the two outputs were multiplexed together, so wither card could paint a picture on the display. Newer notebooks only have one an a half graphics cards - there is no multiplexer any more. Only the low power graphics can refresh the screen image.
This means when the more powerful graphics engine is being used, it has to cooperate with the low power one or you get a black screen.

Xorg has not caught up with this split mode yet. However, as you have a an nVidia card for your second card, look at the Bumblebee project._________________Regards,

Thanks for your careful help, I often used to startx into Gnome 2.6, and it can display applications list after emerge "GDM "to start Xorg last night.

And Gnome 3.2 is not stable for Gentoo, because it display "~x86" in relevant branch, I desired to update Gnome 3.2 and worried the system crash,
so how can I update Gnome 3.2 stable?

I installed Dual Systems Gentoo and Ubuntu on my Notebook now,
I researched Bumblebee project last week, and discovered that it only provide Ubuntu solution, but there is NO Gentoo solution.

BTW: It seems that I am too late to see the News that Linus Torvalds coments on Nvidia graphic card yesterday, Haha, just a joke

There is support for bumblebee on Gentoo in an overlay.
Overlays are outside of the main Gentoo tree and quality can and does vary.

If you want to try Bumblee,

Code:

emerge layman

and follow the instructions in the link above.

For Gnome-3.x, you will either need to switch to Gentoo testing or mix stable and testing.
Both have there advantages and drawabacks.

Testing Gentoo mostly just works. You do get a few nasty surprises from time to time. I can recall three in 10 years.
These can be mitigated by the following
a) do not update just before you must have a working system.
b) set FEATURES="buildpkg". This keeps a binary copy of everything you build, so you can downgrade quickly with emerge -K =package-version.

Mixing stable and testing will cause version collisions when a stable package needs an old version of a library, while a testing package needs a later version of the same library.

I've used testing for about 10 years on a range of architectures._________________Regards,

finally, Could I emerge property nvidia-drivers and unmerge intel or vesa drivers?

Wow! You used on Gentoo almost 10 years, you are a proficient on Gentoo.

I am using Gentoo for Android work developing environment last three years,
and hope that developing environment keeps stable,
I will update Gnome-3.x version until the branch become stable.
